Hi Vivek, You need a kerberos ticket to interact with a secure Hadoop Cluster. To obtain kerberos ticket , do a kinit. More kerberos command are here : http://hadoopsecurity.org/wiki/Useful%20Kerberos%20Commands%20for%20a%20Hadoop%20User
You can also obtain kerberos tickets programatically using keytab. See http://hadoopsecurity.org/wiki/How%20to%20access%20secure%20Hadoop%20cluster%20programmatically%20using%20keytab Other than fetching a ticket, you do not need to change anything. A few useful "How Tos" for a secure Hadoop Cluster are here : http://hadoopsecurity.org/wiki/How%20Tos Let me know if it solves your problem. thanks , Benoy On Sat, Mar 12, 2016 at 7:39 AM, Vivek Mishra <[email protected]> wrote: > Hi, > > Can anyone point me to a reference for running map reduce job or HDFS file > creation over Kerberos secured HDFS cluster( From remote client machine)? > > Spent entire day with different tweaks using UserGroupInformation and > SecurityUtil. > > > > > > ------------------------------ > > > > > > > NOTE: This message may contain information that is confidential, > proprietary, privileged or otherwise protected by law.
